A characterization of the data, including its intended use and limitations.
2009 Capitol Region Council of Governments (CRCOG) Orthophotography is very high resolution, color, leaf off, aerial photography that covers the entire Capitol Region and the Town of Plainville, Connecticut. The coverage area includes the following municipalities in Connecticut - Andover, Avon, Bloomfield, Bolton, Canton, East Granby, East Hartford, East Windsor, Ellington, Enfield, Farmington, Glastonbury, Granby, Hartford, Hebron, Manchester, Marlborough, Newington, Plainville, Rocky Hill, Simsbury, Somers, South Windsor, Suffield, Tolland, Vernon, West Hartford, Wethersfield, Windsor, and Windsor Locks. The ground resolution is 3 inches (0.25 ft) per image pixel and the date of the photography is Spring 2009. The orthophotography is intended to support mapping at 1:1,200 scale (1 inch = 100 feet).
In 2008, the Capitol Region Council of Governments received approval for a Regional Performance Initiative (RPI) grant from the Connecticut Office of Policy and Management to acquire orthophotography. The RPI grants are designed to take advantage of economies of scale that can be realized by regional cooperation and coordination of projects in Connecticut. The RPI grant funded the aquisition of 2009 orthophotogy for the entire Capitol Region and the Town of Plainville, for a total of 30 municipalities. Several additional municipalities also contracted with the vendor to acquire orthophotography at reduced cost due to the size and coordination of the flight. The project was managed by CRCOG, with generous assistance from municipal GIS professionals in the region. In particular, the task of reviewing the quality of the orthophotography produced by the vendor was completed by CRCOG staff and these municipal GIS professionals.
This particular aerial survey of color, leaf off, 3 inch pixel resolution orthophotography provides the ability to map a comprehensive set of detailed planimetric data that includes roads, sidewalks, streets, highways, and alleys including curb lines, edge of paved surfaces or edge of traveled way, utility poles, street signs, highway lane and traffic safety markings, and general feature details as building footprints, decks, pools, reservoirs, tanks, docks, piers, airports, bridges, overpasses, underpasses, railroads, parking lots, driveways, other impervious surfaces, streams, lakes, drainage courses, holding basins, shorelines, other watercourses, vegetation outlines, fence lines, drainage, and other similar construction or terrain features.
This is ideal for identifying features on the ground surface in developed, open, and even wooded areas because leaves on trees and shrubs that normally obstruct the view from above are largely absent. For example, features such as stone walls, dirt roads, and other structures in wooded areas are usually visible and identifiable. Areas of deciduous verses coniferous trees are apparent.
WSP SELLS, Inc. was contracted to provide the 2009 Orthophotography.
